[Bug c/14516] New: [3.4/3.5 regression] -fleading-underscore does not work correctly for file static variables

[ian at wasabisystems dot com]

Compile this:

int i;
static int j;
int foo()
{
  static int k;
  return k;
}

with -fleading-underscore (gcc -S -fleading-underscore foo.c).  The variable k
is compiled as "k.0" with no leading underscore.  This worked correctly in 3.3.

I suspect that this problem also appears in a compiler targeted for sh-elf,
which sets USER_LABEL_PREFIX to "_".  In that case there is no need to use
-fleading-underscore, as it is implied.  The problem came up on the gdb-patches
list, and I tried recreating it using -fleading-underscore rather than building
an sh-elf compiler.
